When an internal fault or environmental anomaly occurs, the Eliwell SB655 C triggers built-in safety routines and outputs visual diagnostic error codes on the display. Common Error Codes
High-temperature alarm. The unit is warmer than the set threshold. AL1: Low-temperature alarm. 6. Installation Best Practices
Probe 2: Defrost termination / Evaporator temperature monitoring.
While this guide covers 95% of typical scenarios, you should keep the original manufacturer’s manual on hand. Official PDFs are available from: The is a universal parametric controller within the
Supports NTC temperature probes, 4-20mA, and 0-10V analogue inputs. Mounting: Designed for standard 32x74mm panel mounting.
: Supports automatic summer-winter changeover and dedicated modes like Communication : Compatible with protocols for integration into BMS networks. Advanced Control
Note: If the setpoint does not flash, the unit may be "Parameter Locked" (see the Pr1 parameter in the manual).
For professionals managing or installing these systems, the is essential for proper configuration, installation, and troubleshooting. What is the Eliwell SB655 C? The Fans run continuously and remain active during defrost
Here is a table of the most critical parameters. Set these correctly to avoid compressor short-cycling or product loss.
: Common codes such as E1 (cell probe error) or E2 (defrost probe error) indicate shorted or interrupted sensors.
A: ELIWELL NTC 10kΩ at 25°C (probe type: NTC103AT) is standard. PTC probes (PtC) are also supported if you change parameter S1P to “PtC.” Do not use PT100 (RTD) probes; they are incompatible.
